问题 I would like to upload files and images using django-channels but i don't have any idea where to start. Seems like there is not much documentation about websockets and file/image uploads. Any ideas? 回答1: I also faced the same problem and I solved it by uploading the the Image/File in S3 bucket. we just need to decode the base64 code and upload the file and return the URL to websocket. We can also provide preview of the image by providing the file type. def file_upload(self, data): # Convert

How do I ensure a Django Channels message is sent immediately without delay?

问题 The idea is to run a background task on the worker.connect worker. While executing the task, I would like to send its progress to a connected client via the notifications Group. The problem: the messages sent to the notifications Group are delayed until the task on the worker is finished. So: both messages 'Start' and 'Stop' appear simultaneously on the client, after a delay of 5 seconds ( sleep(5) ). I would expect the message 'Start', followed by a 5sec delay, followed by the message 'Stop'

问题 I'm trying to incorporate django-channels into my next project but I am having issues debugging. I have tried pycharms debugger and also pdb but it does not hit the breakpoints. 回答1: Take a look into django channels panel. It is a plugin to django debug toolbar. You can add django-channels-panel to this to add channel debug functionality to your project. This ensures that you can channel details when your app is in development mode. https://github.com/Krukov/django-channels-panel Installation

Serving Django Channels In Production-like Setting With Apache Directing Traffic

I have been playing around with Django Channels for a a little bit and I am stuck on how to get it to work outside of a local development server setting. Before someone just pastes a documentation page to me, I have exhausted my search of the Django Channels documentation and everywhere else I could find. I can get the local setup to work fine, but not externally. My philosophy over years has been to never develop with the Django development server ever under any circumstances anyways because of exactly this kind of situation. So here it is: I have a django site that has been served by apache
